Impact buckets are useful, for example, in fracturing rock and other hard material which is to be excavated. Known systems using vibrating mechanisms which are mechanically coupled to a cutting edge assembly do not produce forces high enough to efficiently fracture the rock or other hard material and send destructive vibration forces to the base vehicle. The subject impact bucket mechanism uses an impact hammer which is impact coupled to a cutting edge assembly to fracture rock and other hard material. This results in a force controlled system in which displacement varies with material resistance. The force levels achieved by the impact coupled system are higher than the vibrating system. Thus, the disclosed impact bucket mechanism can produce higher force levels which can more efficiently fracture the rock or the other hard material without sending destructive vibration to the base machine. |
